It's not about solving a problem. It's about solving the same problem slightly better. The reason why new MVC frameworks pop up all the time is because everybody organizes and writes their code differently based on their own use cases and mental model of how things should work. There is no ubiquitous JS MVC framework because to be honest, either the APIs out there are not very good or it's too much overhead to simply pick up and use for a beginner in many cases.
